Claims. 1 o

This invention relates to gun sights, and more particularly, to a gunsight adapted to be used on a shotgun, riiie and other re arms.

A main object of this invention is to provide a shotgun sight ofextremely simple construction which is especially adapted for aiming atmoving targets, such as game, clay pigeons, etc. where the speed of thetarget can be roughly estimated.

A further object of this invention is to provide a novel rear sight fora single or a double barreled shotgun wherein the aiming of the gun atstationary targets or targets moving at approximately known velocitiesis facilitated.

Further objects and advantages of the invention will appear from thefollowing description and claims, and from the accompanying drawings,`

wherein:

Figure 1 is a side elevational view of a portion of a single barrelshotgun provided with a rear sight in accordance with this invention.

Figure 2 is a front elevational view of a gun barrel provided with thesight of Figure 1.

Figure 3 is a horizontal crosssectional View taken through the maintunnel portion of the sight, of Figures l and 2.

Figure 4 is a view corresponding to Figure 2 showing a double barreledshotgun provided with a rear sight in accordance with this invention.

Referring to the drawings, a conventional single barrel shotgun isdisclosed having a barrel I provided with a at top longitudinal rib 2.Mounted on barrel l at a distance which may be between 8 and 18 inchesfrom the eye of the marksman when aiming the gun is a rear sight member3 comprising a longitudinal strip element yIl provided at its ends withloop elements 5 and E adapted to respectively embrace the gun barrel atthe front end and the 'body portion of the gun at the rear end thereofto hold the strip in horizontal aligned position with respect to the rib2. Intermediate the ends of strip element 4 a tunnel member l is formed,said tunnel member being of substantial length, and being of a heightand width approximately equal to the diameter of barrel i. Said tunnelmember 1 is provided with a. cylindrical top portion, vertical sidewalls and a horizontal floor portion including strip element l. A pairof longitudinal side flanges 8, B depend from strip element 4 andsupport tunnel member 1 in vertically spaced relation to rib 2 closelyengaging said rib so that the marksman may sight along rib 2 under thelicor of tunnel member 'i and view the front sight between side flanges8, 8.

Positioned within tunnel member 1 on the ilat oor portion thereof is acircular peep sight element il,l located in the central verticallongitudinal plane of barrel i and substantially midway between the endsof tunnel member 1. At the front end of tunnel member 1 at the oorportion thereof and equally spaced on each side of the longitudinalcentral vertical plane of barrel I are a pair of upwardly projectingpointed sight elements ID, I0. The location of said pointed sightelements IU, I0 is such that an object moving at right angles to themarksman at an approximately known velocity may be aimed at by rstaligning the front sight with the object along rib 2 or through peepsight 9 and then moving the muzzle of the gun carrying the front sightforward until the object is aligned, with one of said pointed sightelements, thus automatically compensating for the motion of the objectduring the time of travel of the shot. Similar compensation may be madefor a moving object traveling at an approximately known greater speed byaligning the object, after preliminary sighting, with one of the sidewalls of tunnel member 1.

A stationary target, or a target moving directly toward or away fromthe'marksman may be aimed at by rst obtaining an approximate alignmenttherewith through the bottom tunnel formed by side ilanges 8, 8 and thenaligning the target with the front sight of the gun as viewed throughpeep sight 9.

Additional pairs of pointed sight elements similar to elements i0, I0may be provided at the iront edge of the Iloor of tunnel member 1 toprovide automatic advance of the gun barrel for targets moving atvarious estimated velocities.

Since tunnel member 1 is of substantial length, said tunnel member actsas a glare shield with respect to peep sight element 9, therebyfacilitating the aiming of the gun under conditions of illuminationwhich might otherwise make it impossible to aim the gun by sightingalong the barrel. When it is desired to remove the sight it may beeasily slipped off the gun, loop members 5 and 6 being normally engagedwith the gun merely by frictional contact. Therefore, by pushing loopmembers 5 and 6 in the direction of the front end of the barrel thesight may be dismounted. The sight may be quickly replaced on the gun bya reverse procedure.

In Figure 4 the sight is shown adapted for a double barrel shot gun. Inthis embodiment the loop members are appropriately formed so that thesight will be located in the central longitudinal vertical plane betweenthe two barrels.

While a specific embodiment of a shotgun sight has been disclosed in theforegoing description, it will be understood that various modificationswithin the spirit of the invention may occur to those skilled in theart. Therefore, it is intended that no limitations be placed on theinvention other than as defined by the scope of the appended claims.

What is claimed is:

1. A rear sightA for a shotgun'. comprising; an elongated tunnel member,means' for' detachably' mounting said tunnel member on the rear portionof a shotgun barrel in vertically spaced rela-- tion to said barrel andextending longitudinal-ly thereof, a peep sight element provided withinsaid tunnel member in the vertical longitudinal plane of said barrel,and-additional sight means, provided at the forward edge portion of saidtunnel member, said additional sight means being later` ally spaced fromsaid vertical longitudinal plane.

2. The structure of. claim' 1,l and. wherein said tun-nel member isprovided withv depending side flanges extending from; theftunnel; baseto the top. portion of said barrel, longitudinally arrangedwithrespecttothe ba-rreksaid side flanges form-- inga. secondary tunnelstructurewith. respect. to

3, A rea-r sight. for a. shotgun: comprising an elongated horizontalstrip: members,v means provided at the ends'l of. said member for`detachably mounting said stripr memberA on. the rear; portion of aishotgun. barrelv in. vertically spacedA relation thereto; anda extendinglongitudinally thereof', alongitudinal. tunnel memberY ofA substantialllengthimount ed. onsaidistrip imenrbenalieep. sightr ,4 elementprovided Within said tunnel member substantially midway between the endsthereof and located in the Vertical longitudinal plane of said barrel,and additional sight means provided at the forward end of said tunnelmember, said additional sight means being laterally spaced from saidVertical longitudinal plane. l

4. The structure of claim 3, and wherein said tunnel member is providedwith depending'vertical side flangesv extending from the floor of theturmel to .the top portion of' said barrel', said side flanges beinglongitudinally arranged with respect tothe barrel and forming asecondary tunnel structure With respect to said top portion of thebarrel.

5. The structure of claim 3, and wherein said additional sight meanscomprises a pair of vertical pointer members projecting upwardly fromthe front edge of the tunnel floor, said pointer members being spaced atequal distances from saidvertical longitudinal plane.
